Slack is a Communication MCP server that lets Claude Code, Cursor, Windsurf and any MCP-compatible AI agent slack channels, messages, and workspace management. Install in 1 minute with mcpizy install slack.
Communication
Slack channels, messages, and workspace management
Connect your Slack account once — MCPizy stores the credentials encrypted and uses them whenever you run a recipe in managed mode.

If Slack doesn't fit your stack, these Communication MCP servers solve similar problems.
The Slack MCP server is an Communication Model Context Protocol server that lets Claude Code, Cursor, Windsurf, VS Code with Copilot, and other MCP-compatible AI agents slack channels, messages, and workspace management. It exposes Slack's capabilities as tools the AI can call directly from your editor or CLI.
The fastest way is the MCPizy CLI: run `mcpizy install slack` and MCPizy will add the server to your `.claude.json` automatically. You can also install it manually by adding an entry under `mcpServers` in `.claude.json` with the command `npx -y @modelcontextprotocol/server-slack` and restarting Claude Code.
Yes. The Slack MCP server is free and open source (see the GitHub repository linked on this page). You may still need a Slack account or API key to connect the server to the underlying service, but the MCP layer itself has no MCPizy subscription cost.
Yes. Any MCP-compatible client works — including Claude Code, Claude Desktop, Cursor (via `.cursor/mcp.json`), Windsurf, VS Code with Copilot Chat, and custom agents built on the MCP SDK. The same install command targets all of them; only the config file path differs.
Once installed, your AI agent can slack channels, messages, and workspace management directly inside your conversation. Typical use cases include asking Claude Code or Cursor to run Slack operations, inspect results, chain Slack with other MCP servers (see our Workflow Recipes), and automate repetitive communication tasks without leaving your editor.
